O1D102 ifm Laser Sensor: Buy the O1D102 O1D Series Distance Sensor with IO-Link

O1D102 Laser Distance Sensor by ifm – Fast ToF with IO-Link

O1D102 is a laser time-of-flight sensor from the ifm O1D series. It measures distance from 0.2 to 3.5 m on black glossy surfaces. Two switching outputs work as PNP or analog. IO-Link adds full digital setup and live data. A class 2 laser and a 50 Hz rate make it quick and precise for moving targets. The zinc die-cast body meets IP 67 for tough plant use.

FAQ

Will a shiny black target still read well?
Yes. The spec covers black glossy surfaces from 0.2 to 3.5 m. Test the actual part to confirm the gap.

How many outputs can I use at once?
Both digital channels work together. Only one may be set to analog mode.

Does the 50 Hz rate lower accuracy?
Accuracy and speed are separate specs. Shorten the range for tight tasks.

Do I need a special master for setup?
Any class A IO-Link master works. You can also run SIO mode without one.

What is a common install mistake?
Mounting near a reflective wall. Tilt the sensor or use a shield to avoid stray light.
